We might add it for the first 3-6 results, my fear is that it's a 
measure that is very bound to the user habits and the database shape. 
for example an adaptive result would appear very fast, an history result 
may take 1ms as well as 1s, since we must scan the whole table to look 
for it, it might be among the first or the last.
Though, I think it's worth a shot, it could still show us 
improvements/regressions even if it might have lots of variation.
I will file a bug for it.
